摘要：
Over the last decade magnetic resonance (MR) imaging has become a well-established method for visualizing myocardial viability. Multislice spiral computed tomography (MSCT) has also recently proven to be a reliable method for assessing the myocardium for this indication. This review extensively describes the changes in acute and chronic myocardial infarction including the differentiation of stunned or hibernating myocardium. This review focuses on delayed myocardial contrast enhancement as a key concept of viability imaging. Myocardial perfusion imaging as well as the use of alternative contrast agents are introduced. Pathophysiology is correlated to the changes observed in MR imaging and MSCT. The clinical impact of the imaging findings is described.
